RAUC v0.4 Released
The RAUC team is proud to announce that we've just released RAUC v0.4!
Beside a few fixes, this version provides some useful new features such as atomic bootloader updates for eMMC, a central storage location for the RAUC system status information and experimental support for using RAUC with the casync chunking tool for delta updates over the network.
Enhancements
- Add barebox-statename key to [system] section of system.conf in order to allow using non-default names for barebox state
- Support atomic bootloader updates for eMMCs. The newly introduced slot type boot-emmc will tell RAUC to handle bootloader updates on eMMC by using the mmcblkXboot0/-boot1 partitions and the EXT_CSD registers for alternating updates.
- Support writing *.vfat images to vfat slots
- Add basic support for streaming bundles using casync tool.
Using the casync tool allows streaming bundle updates chunk-wise over
http/https/sftp etc.
By using the source slot as a seed for the reproducible casync chunking
algorithm, the actual chunks to download get reduced to only those that
differ from the original system.
- Add rauc convert command to convert conventional bundles to casync bundle and chunk store
- Extend update handler to handle .caibx and .caidx suffix image types in bundle
- Added --detailed argument to rauc status to obtain newly added slot status information
- Added D-Bus Methods GetSlotStatus to obtain collected status of all slots
- Extended information stored in slot status files (installed bundle info, installation and activation timestamps and counters)
- Optionally use a central status file located in a storage location not touched during RAUC updates instead of per-slot files (enabled by setting statusfile key in [system] section of system.conf).
- Add write-slot command to write images directly to defined slots (for use during development)
Bug fixes
- Fix documentation out-of-tree builds
- Fixed packaging for dbus wrapper script rauc-service.sh
- Some double-free and error handling fixes
Testing
- Create uncrustify report during Travis run
Code
- Unified hash table iteration and variable usage
- Add uncrustify code style configuration checker script to gain consistent coding style. Committed changes revealed by initial run.
Documentation
- Updated and extended D-Bus interface documentation
- Added documentation for newly added features (casync, central slot status, etc.)
- Fixed and extended Yocto (meta-rauc) integration documentation
- Add link to IRC/Matrix channel
- Some minor spelling errors fixed
